ISO 15705 Intelligent Automatic Touch Screen Control Oxygen Index Tester

I. Advantages of LR-5 intelligent automatic touch screen control oxygen index tester
1. Full-color touch screen control, just set the oxygen concentration value on the touch screen, the program will automatically adjust to the oxygen concentration balance and issue the sound of beep, eliminating the trouble of manually adjusting the oxygen concentration;
2. The stepping proportional valve greatly improves the control accuracy of the flow, and the closed-loop control is adopted. During the test, the oxygen concentration drift program automatically adjusts back to the target value, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test and greatly improves the test accuracy.

Ii. Main technical parameters of LR-5 intelligent automatic touch screen controlled oxygen index tester

1. Using imported oxygen sensor, digital display oxygen concentration without calculation, more accurate and more accurate, range 0-100%
2. Digital resolution: 0.1%
3. Measurement accuracy: 0.1 level
4. The touch screen setting program automatically adjusts the oxygen concentration
5. One-key calibration accuracy
6. One-bond ratio concentration
7. Stable oxygen concentration automatic alarm sound
8. With timing function
9. Experimental data can be stored
10. Query historical data
11. Historical data can be cleared
12. Optional whether to burn 50mm
13. Air source fault prompt
14. Oxygen sensor fault prompt
15. Tips for wrong connection of oxygen and nitrogen
16. Oxygen sensor aging tips
17. Standard oxygen concentration input
18. Diameter of combustion cylinder can be set (two common specifications are optional)
19. Flow regulation range: 0-20l /min (0-1200l /h)
20 quartz glass tube: two specifications either (diameter 75 mm or inner diameter or greater or higher 85 mm)
21. Gas flow rate in combustion cylinder: 40mm± 2mm/s
22. Overall dimensions: 650mm * 400 * 830mm
23. Pressure gauge accuracy 2.5, resolution: 0.01mpa
24. The test environment: the environment temperature: room temperature ~ 40 ºC;, relative humidity: 70%;
25. Input pressure: 0.25-0.3mpa
26. Working pressure: nitrogen 0.15-0.20mpa oxygen 0.15-0.20mpa
27. The specimen holder can be used for soft and hard plastics, various building materials, textiles, fire doors, etc
28. Propane (butane) ignition system, the ignition nozzle is made of a metal, the end has Φ 2±1 mm inner diameter nozzle, can be bent freely.Can be inserted into the combustion tube to ignite the sample, the flame length: 16 4mm, the size of 5mm-60mm can be adjusted freely,
29. Gas: nitrogen and oxygen for industrial use with purity of > 99%;(the purity of industrial oxygen in user-provided/normal gas stations is generally between 99.2% and 99.3%).
30. Power requirements: AC220 (+10%) V, 50HZ
31. Maximum power: 150W
32. Self-supporting material sample holder: it can be fixed in the position of the axis of combustion cylinder and can hold the sample vertically
33. Non-self-supporting material sample holder: it can fix two vertical edges of the sample on the frame at the same time (optional/applicable to soft non-self-supporting materials such as textiles).

Iii. Design standard
GB/T 2406.2-2009
Tips: when testing oxygen index tester, one bottle of industrial-grade oxygen/nitrogen of no less than 98% should be used as gas source. As the above gas is high-risk transport, it cannot be used as accessories of oxygen index tester, so it can only be purchased from local gas stations of users.(in order to ensure the purity of the gas, please purchase it at a local regular gas station)
